AXially disposed on the inner side of the disk 24 is a projection 30 which is adapted to enter the ports and i3 when all of the medicant has been forced from the cylinder 22 and the disk abuts the closed end of the magazine. In

. this position of the disk, the projection 30 Vwill operate to lock the valve V againstrotation, as an indication to the operator that the cartridge has been emptied of its contents.

In the operation of the insufflator, a lled cartridge C, from which the wrapper 25 and cap siton by grasping the magazine in one hand and rotating the bulb yB with the other, thespring 26 will forcev a small quantity o f the medicant powder from the cartridge through the registering'ports 10 and 13 into the bore of the tube l2.

:The tube 12 is now reversely rotatedto move the port 13 outofregistration with the port V10. The small'quantity ordose. of powder in the tube l2` can be now blown therefrom by'r compressing the bulb B.V Any suitable form of applicator (notshown) can be applied to the free end of the tube 10 for insertion into Athe orifice of the body to be treated. 'Itwillkbe understood that the medicant powder is fof acharacter to render it non-packing sothat eachftime'the valve is opened, thesp'ring 26 and the disk 24 will coact to forceta small quantity or dose of the powder from the cartridge into the bore of the valve tube 12 for ejectionas desired. y

The use of the cartridge and the manner in which it is associated with the device render it possible toutilize a soft and amorphous powder (non-crystalline), rather than the ordinary crystalline powder required for` the present types of ins'uiilators which have to be packed full by repeatedly pressing upon'the powderin the manner of filling a capsule. By the use of the soft and amorphous powdenproper insuiation is secured, with a complete diffusion of the particles on ythe membrane where they almost instantly dissolve and provide medication for hours, as compared 50 with minutes when the same ingredients are applied iny solution.
